Augustine was a facility that held mutants against their will. They used them as test subject to see how they were who they were. Scientist poke and probe them like animals so that they could see how they function and how to be like them. They would dissect those who had the healing ability. They would open them up ,while the person was still awake, and pull out their intestines, cut off limbs and infect them with deadly diseases.
One of those test subjects was a 12 year old girl named Veronica. She was taken from an orphanage that had burned down from a freak accident. Augustine swooped in and took in the kids that had the X gene. Those who didn't were killed by getting gassed in their room as they slept.
Veronica's sister was one of them. She was only nine but that didn't stop them. When Veronica heard the news, She just shut down. She wasn't aware of what was going on around her. When it was her turn for experimentation, She didn't care. It was like she turned off her emotions.
They have broke her physically, mentally and emotionally to the point where she doesn't even recognise herself when she looks in the mirror. All she sees is a girl with eyes that hold so much pain, anger and darkness. She remembers how she used to be so carefree and filled with life but now she looks like death himself.
It would take years until she finally felt the sun on her skin and be able to breath in the fresh air, but for now she's locked in a prison both literally and figuratively.
